Abstract: Biomass energy is a hot topic in the energy sources and eco-environment fields. This paper summarizes its using status quo. Besides, four hot topics of biomass energy were expatiated, which were the exploiting potential, the effect on eco-environment, the conversion technologies and the feasibility analysis of utilization and its developmental prospects. The barriers of exploiting biomass energy which need to be solved were analyzed briefly in the end. This review can be helpful to form a scientific knowledge of biomass energy research. Biomass energy will have a bright future in the drag of the demand of energy resources, the protection of eco-environment and the development of economy.
